Hybrid tea rose plant named ‘Poulren033’

ABSTRACT

A new garden rose plant of the Hybrid Tea class which has abundant, red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrida.

Variety denomination: ‘Poulren033’.

This application claims priority to Plant Breeder's Rights ApplicationNumber 2020/2247, which was filed at the Community Plant Variety RightsOffice in the European Union on Sep. 21, 2020, the contents of which arehereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2013 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulren033’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. The malepollen parent plant has orange yellow blended flowers while the newvariety has red flowers. The female seed parent plant has flowers with adiameter of 80 mm while the new variety has a flower diameter of about100 mm.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant red flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulren033’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2013 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulren033’ was selected in thespring of 2014 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulren033’ by rooted cuttings was first doneby Mogens N. Olesen in the nursery in Fredensborg, Denmark in July,2014. This initial and other subsequent asexual propagations conductedin controlled environments have demonstrated that the characteristics of‘Poulren033’ are true to type and are transmitted from one generation tothe next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulren033’, as observed in itsgrowth in a field nursery in Linn County, Oreg. Observed plants are 2years of age, and were grown on their own roots. Color references aremade using The Royal Horticultural Society (London, England) ColourChart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘Poulren024’, U.S. Plant Pat. No. 26,792 are compared to ‘Poulren033’ inChart 1.
